要約(日本語): In this paper, an assessment of the effect that an overhead conductor’s thermal characteristics, particularly the resistance-temperature dependence, has on the Optimal Power Flow (OPF) solution is carried out. It is confirmed that conductor temperature has a small effect on power flow, but a comparatively larger effect on transmission loss. Therefore, while inclusion of the conductor’s thermal characteristics to set the line rating with Dynamic Line Ratings (DLR) could increase line loadability, the effect on the formulation of the OPF problem and hence its complexity is minimal.
